Heh, just because something doesn't kill you instantaneously doesn't mean it's safe, especially long-term. I figure that any amount of a toxic substance is too much, if it can be avoided.
But, unfortunately, it sounds like if a product to avoid making excessive amounts of carbon monoxide exists it is not readily accessible. Drat.
